Abstract

Cognitive radio networks that employ the dispersed spectrum utilization as spectrum access method are called dispersed spectrum cognitive radio networks. In this paper, we derive the effective transport capacity of adhoc dispersed spectrum cognitive radio networks in which the nodes are distributed in three dimensional (3D) configurations. The analysis is performed considering a cubic grid distribution for the node configuration and inter-node interference (INI). Numerical results are provided to show the effects of node distribution, fading, and modulation on the effective transport capacity of adhoc dispersed spectrum cognitive radio networks.
